Hi Mark,

 

I have a directory containing all of the Point Grey firmware I have downloaded.

 

corvette:~/areaDetectorVendor/PointGrey/Firmware>ls -ltr

total 1092

drwxrwxrwx 3 epics epics     142 Oct 11  2015 GS3-PGE-1.09.3-00

drwxrwxrwx 3 epics epics     139 Oct 15  2015 GS3-U3-1.15.3-00

drwxrwxrwx 2 epics epics     110 Oct 15  2015 GS3-U3-2.08.3-00

drwxrwxrwx 3 epics epics      56 Oct 15  2015 GS3-U3-2.11.3-00

drwxrwxrwx 2 epics epics     109 Oct 15  2015 GS3-U3-2.14.3-00

drwxrwxrwx 3 epics epics      58 Oct 15  2015 BFLY-PGE-1.43.3.0

drwxrwxr-x 3 epics epics     103 Jun  7  2016 GS3-U3-2.23.3-00

drwxrwxrwx 3 epics epics      34 Jun 20  2016 GS3-U3-2.24.3-00-23S6

 

Note that for version 2.23.3 it is a generic version for the entire Grasshopper3 USB-3.0 family of cameras.  For 2.24.3 however I have a version that is specific to the 23S6 model.  I suspect that what they are doing is releasing model-specific versions so they can take advantage of new features or fix bugs quickly, and then as time permits they release a new generic version for all models in that family.

 

I am quite certain I have accidentally tried to flash an incompatible version into a camera, and their flashing software was smart enough to prevent this.  The only problem I have had with their flashing software is with GigE cameras where it would fail if the camera was on a shared network. I had to temporarily make a direct connection from my PC to the camera.  I think the flashing software must not deal well with collisions or something.  I've had no problems flashing USB-3.0 cameras.

Mark - Question

 

Historically you have mentioned in Tech-Talk that PointGrey only tends to post the latest firmware on their website once *all* the cameras in a specific model class are know to work. So asking support for the latest versions is suggested, since the posted firmware may be very old and buggy.

 

I did that recently and asked what the firmware was for 3 grasshopper modules and support responded with

 

=============

I have attached a dropbox link below for your new firmware. This is compatible

with all GS3-U3 cameras.

 

gs3-u3-2.31.3-00.ez2

=============

 

However, even the PointGrey website says that

 

=============

Grasshopper3 USB3 Firmware

This is the latest version of firmware for the Grasshopper3 USB3 cameras. Note that the firmware is model specific.

=============

 

Should I assume that Support is correct and that this is indeed a one size fits all firmware package, or at least contains multiple firmware images that will install as required, or is a single image most probably not to work at all. If not, does the camera flashing software have enough intelligence not to update an incorrect firmware? Or be able to restore a legacy firmware if the process fails? I do not have a camera in hand to test and wanted an expert opinion before I walk over to a beam line and start flashing hardware.
